Abstract (en)
[origin: DE19746106A1] The valve body (22) rests against a first (6) and second (15) side of a passage. The pressure difference according to the direction reinforces the sealing pressure of the valve body against the first or second passage-side. The valve body is rotationally symmetrically formed in an especially membrane like dish. The valve body is positioned between holders (8,9,17) protruding from opposite sides into a valve housing.
